Explanation:

Commas are used to enclose items in professional titles and academic.  And the second element in a geographical name is usually separated by the use of a comma.  The placement of commas in a sentence follows some usage rules.  By punctuating the academic title "PhD," there is a separation of the title from the titleholder.  In the same light, the separation of the first geographical name indicates that "Forth Worth" is a part of "Texas."  Without the comma, it will look as if there was an absolute location named "Forth Worth Texas," and not that "Forth Worth" is in "Texas."
